Manchester United received a 4-1 bashing in the hands of Manchester City at the Etihad Stadium.
United legend Roy Keane described the match as a game between men and boys, as he was frustrated with the display from Ralf Rangnick’s side.
Rangnick on his side believes that Manchester United played well for about an hour before collapsing as City scored their third goal.
Speaking after the game, Rangnick said: “I think it was a good first half, even the first 60 minutes were okay, but the first half was good. We had our moments, we could have scored one or two goals more in the first half.
“Whenever we were in possession of the ball, we showed that we could create problems for them, the same is true with our transitional moments, but, in the end, they scored two goals and we only scored one.
“So at half-time, it was clear for us that we needed to try to score at least one if not two more goals, and once they scored the third one, which was a brilliant corner kick, we just have to admit that, it was difficult to defend it, then it was almost over.
“This goal killed us off because then against a team like Manchester City, the best team in the world in possession of the world, if you then still try to chase the ball high up, then you take the risk to concede another two or three more goals.”
